I have a simple java applet that retrieves an image from a server and prints it out. The only problem is that I get the following java security warning:

error message

Researching on this site and all over the web, some people suggest that I sign the applet (I tried that to no avail) and others suggest that I Modify a local java security setting but that isn’t feasible for my clients.

Not only do I get this warning at the start of my applet, but seemingly any time the code attempts to interact with the printer, the dialog re-appears. Also, note that there is no checkbox next to ‘Always allow this applet to access the printer’. These symptoms show on any browser.

How do I get java to respect the users choice to allow it to send jobs to the printer?

    You might use the JNLP API services in a sand-boxed applet in a plug-in 2 JRE. They will still prompt the user each first time they go to print, but should also put an ‘always allow’ check-box on the dialog (though it really only applies for that run). See a demo. of the PrintService.

    See also the applet info. page that includes a link on the Next Generation in Applet Java Plug-in Technology which “..brings new abilities to applets: such as .. allowing embedded applets to gain full access to the services of Java Web Start.”
